Figure Lengend Snippet: Endovascular treatment of dural arteriovenous fistula (a-d) and postoperative imaging (e-h) (a) Working angle view of the left external carotid angiography through a 4 Fr. guiding sheath (as seen in panel c: *) showing a dural arteriovenous fistula. (b and c) A microcatheter (single arrowhead) is guided to the shunt point using a 45° pre-shaped distal access catheter (double arrowhead) through a 6 Fr guiding sheath (triple arrowhead) which is placed in the left internal jugular vein. Another 6 Fr guiding sheath (double arrow) is also placed in the left internal jugular vein to guide a balloon catheter (single arrow) near the shunt. (d) The balloon catheter is inflated to support the microcatheter and to avoid deviation of the coil to the jugular vein. Coiling into the shunt pouch is performed through the catheter. (e and f) Axial and coronal view from cone-beam computed tomography images showing the detachable coils implanted in the shunt pouch within the bone. (g and h) Frontal and lateral view of the left external carotid angiography showing that the shunt is completely occluded.
Article Snippet: The first detachable coil (Target 360 nano, 2.5 mm secondary diameter, 4 cm length; Stryker, Athens, MI, USA) passed through the shunt point and reached the feeder side; hence, it was anchored to the arterial side and coiled continuously to the venous side.
Techniques: Imaging, Computed Tomography
